I oughta do a presentation on ReactJS then - it's really cool.

Probably more of a "handle" than "avoid" situation.


I'll see how to incorporate that into a presentation without doing *too* 
deep a dive.


For now, think of asynchronicity: a variable in-scope at declaration 
might not be available at invocation, so by using a (normally anonymous, 
aka "lambda"-style, in-line) function, it'll get the parameters and be 
able to use then whenever its turn to run occurs.

That's an off-the-top-of-my-head response, hopefully will help a bit.


There are two classic computer problems:

     1. cache invalidation
     2. naming things
     3. off by one errors













     0. asynchronous events
